JavaFX WebView up call from JavaScript doesn't work

由 萝らか妹 提交于 2020-05-13 06:28:08
问题 I have a JavaFX WebView and want to call the method "hello" of the class "JavaBridge" from "test.html" displayed in the webview. Why doesn't this work? I making sure that the "bridge" object only be added to the window.object when the page has been fully rendered, so that is probably not the problem. I can't see any problem with the HTML either. Here is the HTML code ("test.html"): <html> <head> </head> <body> <a href="#click" onclick="bridge.hello()">call java</a> </body> </html> And here is

JavaFX 3D Colouring faces … again

由 混江龙づ霸主 提交于 2020-05-13 04:55:14
问题 I studied this question, but I still don't get it. The shortest possible code below shows a Pyramid totally grey, whereas I try to give the 6 triangles making up the pyramid different colors. So ... why don't these colors show up? Note that I borrowed the getTexCoords().addAll(..) statement from that question, but clearly I still am doing something wrong. Is it the uv mapping ? What is that anyway? I have seen a topological explanation ( sphere <-> map ), but what has that got to do with

How to create tabs with icons in JavaFX

由 亡梦爱人 提交于 2020-05-09 19:43:18
问题 I want to create tabs panel with icons similar to the Firefox configuration panel with JavaFX: Is there any example which I can use to see how to implement this? 回答1: Tabs, like many other elements in JavaFX, have a method called setGraphic(Node value) , in which you can put any JavaFX node.

问题 This question already has answers here : What is the recommended way to make a numeric TextField in JavaFX? (22 answers) Restricting a TextField input to hexadecimal values in Java FX (3 answers) Closed 8 months ago . I have a credit card page in my java fx program.

I have tried changing it from String to integer, but that doesn't

JavaFX的窗体为“StageStyle.UNDECORATED”时，如何使用鼠标移动窗体

由 左心房为你撑大大i 提交于 2020-05-05 23:56:41
如题，因为“StageStyle.UNDECORATED”将会title bar隐藏，用户无法使用鼠标移动窗体。需要通过增加鼠标的“Pressed”、“Dragged”事件处理获取鼠标信息来移动窗体。具体代码如下。 /** * @package ch04 * @date 2020/5/5 * @author qiaowei * @version 1.0 * @description */ import javafx.application.Application; import javafx.scene.Scene; import javafx.scene.control.Button; import javafx.scene.control.Label; import javafx.scene.input.MouseEvent; import javafx.scene.layout.VBox; import javafx.stage.Stage; import javafx.stage.StageStyle; public class DraggingStage extends Application { public static void main(String[] args) { launch(args); } @Override public void start

Event listener for multiple selection in a JavaFx listview

由 ＊爱你＆永不变心＊ 提交于 2020-05-01 04:21:24
问题 I have a JavaFX listview in my code and multiple items can be selected. I have already figured out which event listener I need to use when an item is selected but this listener isn't always triggered when i deselect an item. So my question is, is there an event listener for both selecting and deselecting items? This is the event listener I'm currently using: lvLijst.getSelectionModel().selectedItemProperty().addListener(new ChangeListener<String>() { @Override public void changed
